Hi Carol, I'm sorry to hear that cara is going to need operations for her eyes. Is her vision OK other than the eye being turned inward?
I've rocked and walked Yasin to sleep many times. When he was a newborn I used to follow the feed play sleep routine and put him down when he was drowsy and he just seemed to learn to put himself to sleep without my help but then we went on holidays and mucked up his routine and since then he's needed a bit of help. He's getting better again but he still needs his hammock bounced. Sometimes I sing to him. They say that if you always follow the same routine before putting them down it help them to learn its sleepy time and some people use a sooothing CD or tape as a sleep trigger. Maybe if you visit your echn she could help you with some strategies.
